margin-top: 0px; margin-bottom: 0px; padding: 0px; box-sizing: border-box;">及时清理麦田厢沟、腰沟、围沟，做到 “ 三沟”相通，降低土壤含水量，提升地温，为根系生长、营养吸收利用和麦苗恢复生长创造良好条件，达到养根护叶的目的。</p><p style="text-wrap: wrap; margin-top: 0px; margin-bottom: 0px;

margin-top: 0px; margin-bottom: 0px; padding: 0px; box-sizing: border-box;">早播旺苗如出现主茎和大分蘖冻死现象， 应根据田间苗情和冻害发生情况，追施适量尿素。对中度冻害田块（叶片干枯一半左右、主茎死亡率10%～20%），亩施尿素5公斤，对重度冻害田块（叶片干枯75%以上、主茎死亡率 20%～40%以上），亩施尿素7～10公斤，对特重度冻害小麦田块（叶片全部干枯，主茎死亡率超40%以上），亩施尿素12～15公斤，同时叶面喷施磷酸二氢钾（或芸苔素内酯或两者混合液），促进受冻麦苗尽快恢复生长，促分蘖成穗，降低冻害损失。</p><p style="text-wrap: wrap;
